Heikki Krogerus 1571875bee ACPI / platform: Add support for build-in properties
We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.

To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

Srinivas Pandruvada c11dd70fd7 ACPI / DPTF: move int340x_thermal.c to the DPTF folder
Since DPTF has its own folder under ACPI, move this file also there.

Srinivas Pandruvada 6256ebd5da ACPI / DPTF: Add DPTF power participant driver
This driver adds support for Dynamic Platform and Thermal Framework
(DPTF) Platform Power Participant device (INT3407) support.

This participant is responsible for exposing platform telemetry such as:
    max_platform_power
    platform_power_source
    adapter_rating
    battery_steady_power
    charger_type

These attributes are presented via sysfs interface under the INT3407
platform device:
$ls /sys/bus/platform/devices/INT3407\:00/dptf_power/
    adapter_rating_mw
    battery_steady_power_mw
    charger_type
    max_platform_power_mw
    platform_power_source
    `
ACPI methods description used in this driver:
    PMAX: Maximum platform power that can be supported by the battery in
          mW.
    PSRC: System charge source,
            0x00 = DC
            0x01 = AC
            0x02 = USB
            0x03 = Wireless Charger
    ARTG: Adapter rating in mW (Maximum Adapter power) Must be 0 if no
          AC adapter is plugged in.
    CTYP: Charger Type,
            Traditional : 0x01
            Hybrid: 0x02
            NVDC: 0x03
    PBSS: Returns max sustained power for battery in milliWatts.

The INT3407 also contains _BTS and _BIX objects, which are compliant to
ACPI 5.0, specification. Those objects are already used by ACPI battery
(PNP0C0A) driver and information about them is exported via Linux power
supply class registration.
